(elf_finalize_dynstr): Finalize DT_AUDIT and DT_DEPAUDIT strtab entries. (elf_link_add_object_symbols): Set dt_audit target data when finding a DT_AUDIT. * bfd-in2.h: Regenerate. * bfd-elf.h: Add dt_audit to elf_obj_tdata, and elf_dt_audit macro. ld/ * emultempl/elf32.em (gld${EMULATION_NAME}_add_options): Add --audit, --depaudit, and -P options. (gld${EULATION_NAME}_handle_options): Ditto. (gld${EULATION_NAME}_list_options): Ditto. (gld${EMULATION_NAME}_append_to_separated_string): New function for handling rpath-like colon separated strings. (gld${EMULATION_NAME}_before_allocation): Pass the audit and depaudit libs to bfd. Propagate DT_AUDIT from needed libs to depaudit. * ld.texinfo: Document new options. ld/testsuite/ * ld-elf/audit.exp: New. * ld-elf/audit.rd: New. * ld-elf/depaudit.rd: New. * ld-elf/depaudit2.rd: New. --- ld/ld.texinfo | 22 ++++++++++++++++++++++ 1 file changed, 22 insertions(+) (limited to 'ld/ld.texinfo') diff --git a/ld/ld.texinfo b/ld/ld.texinfo index dca4068..e17d3fc 100644 --- a/ld/ld.texinfo +++ b/ld/ld.texinfo @@ -364,6 +364,17 @@ argument must be one of the strings @samp{archive}, @samp{shared}, or @samp{-Bstatic}, and the other two keywords are functionally equivalent to @samp{-Bdynamic}.
